Dyckia platyphylla L.B.Sm.
Dyckia platyphylla is an attractive plant that grows up to 8 inches (20 cm) tall, forming clusters of rosettes. Leaves are short, wide, glossy, deep green, and blush bronze to purple in full sun. They are covered in silvery scales beneath and attractive whitish teeth along the margins. Rosettes are up to 1 foot (30 cm) in diameter. The up to 3 foot (90 cm) tall stalks of yellow-orange flowers appear from spring to summer.
USDA hardiness zones 9b to 11b: from 25 °F (−3.9 °C) to 50 °F (+10 °C).
How to Grow and Care
Dyckias are not technically succulents, as they do not store water in their leaves like true succulents. They are xerographic and survive long periods without water by going dormant. Their rosette of thick, succulent leaves will eventually wilt, but recovery is rapid when watering is resumed.
Most of the plants survive in warm regions with heavy rainfall for half the year and very dry conditions the rest of the time. This makes Dyckia care slightly challenging, as getting the right balance of moisture to keep the plant happy may be difficult. The growing conditions in their natural setting should be mimicked as much as possible.
In their native region, it is not uncommon to find some forms growing on top of rocks near the water. Water and the cycle of the monsoon season are important features to Dyckia health. They are used to rather poor soil when they grow in-ground and should be planted in a good succulent mixture.

Dyckia platyphylla is endemic to the State of Bahia in eastern Brazil. This plant has reportedly never been found in its natural habitat, and there is speculation that it is a hybrid, maybe even involving Dyckia marnier-lapostollei and Dyckia brevifolia.
